No, saying that e2e encryption makes users _less_ safe is completely dishonest, nothing is fine about this.

The logic of "anything is better than before" is also fallacious.

Depends on your definition of "safe". Imagine an adult DMs a nude photo to a minor (or other kinds of predation).

If it's E2EE, no one except the sender and receiver know about this conversation. You want an MITM in this case to detect/block such things or at least keep record of what's going on for a subpoena.

I agree that every messaging platform in the world shouldn't be MITM'd, but every messaging platform doesn't need to be E2EE'd either.

  • The receiver has a proven and signed bundle, that they can upload to the abuse report. So the evidence has even stronger weight. They can already decrypt the message, they can still report it.

    • Yes, but this leaves the only way to identify this behavior as by reporting from a minor. I'm not saying I trust TikTok to only do good things with access to DMs, but I think it's a fair argument in this scenario to say that a platform has a better opportunity to protect minors if messages aren't encrypted.

      I'm not saying no E2E messaging apps should exist, but maybe it doesn't need to for minors in social media apps. However, an alternative could be allowing the sharing of the encryption key with a parent so that there is the ability for someone to monitor messages.

  • SimpleX handles this by sending the decryption keys when the receiver reports the message.

  • Keeping children safe and prosecuting are too different concepts, only vaguely related. So no, being able to track pdfs doesn't make children safer. What keeps them safe is teaching them safe communication habits and keeping them away from things like Tiktok.

    We shouldn't make the world a worse place for every one because some parents can't take care of their children.

      See also: That time the FBI took over a CSAM site and kept it running so they could nab a bunch of users.

  • Ugh. The kids aren't even safe from the people making, and enforcing laws. This argument should be long over for anyone with eyes or ears.

  • Imagine Hamas are your government and want to figure out who's gay. You don't want a MITM in case they can do this.

    Pick your definition of safe.

    • In that case don't use Tiktok dm's to discuss your sexuality. I think it is strange that people feel like they have to be able to talk on sensitive topics over every interface they can get their hands on.

      Similarly in "traditional" media you may not want to discuss such private conversation on a radio broadcast. Perhaps you would rather discuss it on the phone or over snail mail as there is more of an expectation of privacy on those medium.

    • This is fine if you have TLS encryption and the platform is not local.

      Sure, they can fabricate some evidence and get access to your messages, in which case, valid point.

It makes certain users less safe in certain situations.

E2E makes political activists and anti-chinese dissidents safer, at the cost of making children less safe. Whether this is a worthwhile tradeoff is a political, not technical decision, but if we claim that there are any absolutes here, we just make sure that we'll never be taken seriously by anybody who matters.

  • Claiming e2e makes children less safe is flat out dishonest. And the irony of you criticising “absolutes” after trying to pass one is just delicious.

well having no e2e encryption is safer than having a half-baked e2e encryption that have backdoor and can be decrypted by the provider.

and for tiktok's stance, I think they just don't want to get involved with the Chinese government related with encryption (and give false sense of privacy to user)
